Windows Print Vulnerability: Disable Printer Connection


In early July 2021, a critical Microsoft vulnerability was identified and, in line with actions recently taken by other universities, colleges, and organizations, the University of Windsor was required to disable all printing services on campus and University managed devices. This Microsoft vulnerability also affects unmanaged devices used by UWindsor community members. If you know your device is unmanaged, or you have identified that your printers are still connected, please follow the steps below to disable them manually.


To disable your printers:

  1. In bottom left corner of screen in the Search bar, type "Services."
  2. Click the Open link.
  3. Scroll through the alphabetized list and right click Print Spooler.
  4. In the drop-down list, click Properties
  5. In the Print Spooler Properties pop-up window, on the General tab, change the Startup type to "Disabled."
  6. If the Service status reports "Running", click the Stop button to stop it.
  7. Click the Ok button.
